Commissioned the 3rd 600 MW Unit of the 2,400 MW Jharsuguda
power plant and synchronized the 4th Unit

Merger with Sesa Goa Limited and Vedanta Group consolidation
announced, expected to complete in CY 2012

Zinc - India

Mined Zinc-Lead metal production was 223,000 tonnes in Q4, 7% higher
than Q3. During the quarter, the Sindesar Khurd (SK) mine ramped up to
contribute a record 24,000 tonnes metal-in-concentrate. For the full
year, mined Zinc-Lead metal production was marginally lower at 830,000
tonnes.

Mined Zinc-Lead metal production in FY 2012-13 is expected to be
slightly higher than FY 2011-12. In line with the mine plan for Rampura
Agucha, production in first half of FY 2012-13 is expected to be
marginally lower than corresponding period in FY 2011-12, but will be
more than made up in second half of FY 2012-13. SK mine ramped-up to 80%
utilization in Q4 and will deliver volumes near its capacity in FY
2012-13.

Refined Zinc production was marginally lower at 190,000 tonnes in Q4,
and 6% higher at 759,000 tonnes for the year. Lead production in Q4 was
110% higher at a record 37,000 tonnes primarily due to the ramp-up of
the new 100 ktpa Dariba Lead smelter, which contributed 18,000 tonnes.

With the Rajasthan smelters fully ramped-up and operating at high
efficiencies, during the quarter it was decided to ramp down the 35-year
old Vizag Zinc smelter, which had a relatively higher cost and
contributed 28,000 tonnes of refined Zinc production during the full
year.

Silver production was at a record 88 tonnes in Q4, 77% higher as a
result of ramp-ups of the SK mine, the new 100 ktpa Dariba Lead smelter
and the new Silver refinery. Silver production for the full year was 35%
higher at 242 tonnes.

Zinc – International

In Q4, total production of Zinc-Lead metal-in-concentrate and Zinc metal
was 106,000 tonnes, which included 71,000 tonnes of Zinc and Lead
metal-in-concentrate (MIC) at Lisheen and BMM and 36,000 tonnes of
refined Zinc at Skorpion, in line with earlier years.

For the full year, total production of Zinc and Lead
metal-in-concentrate and Zinc metal was 444,000 tonnes, which included
299,000 tonnes of Zinc and Lead metal-in-concentrate (MIC) at Lisheen
and BMM, and 145,000 tonnes of refined Zinc at Skorpion.

Copper ― India and Australia

Copper cathode production at the Tuticorin smelter was 80,000 tonnes in
Q4, in line with the corresponding prior period. For the full year,
copper cathode production was 326,000 tonnes.

The first 80 MW unit of the captive power plant at Tuticorin has
achieved mechanical completion in Q4 and will be synchronised in the
current quarter.

Mined metal production at our Australian mines was 5,000 tonnes and
23,000 tonnes during Q4 and the full year, respectively, in line with
the corresponding prior periods.

Aluminium

Aluminium production at 245 ktpa BALCO-II smelter was 62,000 tonnes, in
line with the corresponding prior quarter. The smelter operated at its
rated capacity for the full year.

The first metal tapping from the 325 ktpa BALCO-III Aluminium smelter is
expected by Q3 FY 2012-13. The first 300 MW unit of the 1200 MW captive
power plant at BALCO will be synchronised in the current quarter.

We continue to work towards the second stage forest clearance for the
211 mt BALCO coal block, following the Environment Appraisal Committee
(EAC) approval received in November 2011.

Power

Power sales were 2,166 million units and 7,579 million units during Q4
and the full year, as compared with 1,040 million units and 2,680
million units during the corresponding prior periods, respectively, as
the three new 600 MW units of the Jharsuguda 2,400 MW power plant come
into operation. During the quarter, Unit-3 started commercial production
and Unit-4 was synchronised.

Work at the 1,980 MW power project at Talwandi Sabo is progressing well
and the first 660 MW unit is on track for synchronization in Q4 FY
2012-13. The 150 MW wind power expansion at HZL was completed during the
quarter, taking our wind power generation capacity to around 274 MW.

Skorpion was acquired in Q3 FY 2011. BMM and Lisheen were acquired
in Q4 FY 2011. Numbers for Q4 and FY 2011 are post acquisition.

4.

Including production under trial run of 209 million units in Q4 FY
2012 vs 352 million units in Q4 FY 2011, and 926 million units in FY
2012 vs 646 million units in FY 2011
